– To verify correct melting of the metallic load realized in the sintered one.
– Indispensable to have maintained for 1 hour, 50ºC above the nominal temperature of strain.
– Check thtaa the vent-walls is in good condition and there is no crack formation. If any apply a plastic mass in the zone as INSEPLAST 70 PF.
– To verify that quartzite expansion has been corrected
– Do not recarburate with low feet of baths in the nascent linings.
– In the first strain and successive strains, empty the furnace and verify the superficial aspect of the lining. It must be homogeneous and exempt from cracks.
– To assure that in the deslagging practice, the permanency time of the slag coagulant is strictly necessary.
